Abstract
Description
Technical Field
[0001] This utility model relates to the field of signal transmission and storage technology, and in particular to a sliding rail type SIM card holder. Background Technology
[0002] A standard SIM card holder has a convex, round PIN pin. The PIN pin is assembled into a plastic card holder, and then a metal shell is attached to the outside of the plastic card holder to position the SIM card. When installing a SIM card, forcibly pushing the SIM card into the card holder can cause it to become loose, which may lead to unstable signal. Also, the SIM card is not easy to remove after it is inserted.
[0003] Based on the above defects and shortcomings, it is necessary to improve the existing technology and design a sliding rail SIM card holder. Utility Model Content
[0004] The main technical problem solved by this utility model is to provide a sliding rail type SIM card holder, which solves the problems of SIM card loosening and difficulty in disassembling.
[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a sliding SIM card holder is provided, which includes a housing, PIN pins, a cover plate, and a PCB printed circuit board. The top surface of the housing has a SIM card slot for placing a SIM card. Each side of the housing has a row of PIN pin slots communicating with the SIM card slot. PIN pins are placed in the PIN pin slots. The upper antenna of the PIN pins protrudes from the PIN pin slots and is used to contact the SIM card contacts. The lower antenna of the PIN pins is connected to the PCB printed circuit board at the lower end of the housing. Mounting parts are provided on both sides of the housing extending upwards. A cover plate is slidably mounted between the two mounting parts. The bottom surface of the cover plate extends downwards and has a protrusion for pressing the SIM card.
[0006] Preferably, the two mounting portions are provided with sliding grooves for sliding the cover plate on their opposite surfaces, and the cover plate is provided with slider portions placed in the sliding grooves on both sides. The mounting portion at the top of the sliding groove is also provided with a limiting groove for limiting the sliding trajectory of the cover plate. The cover plate is also provided with limiting blocks on both sides, and the limiting blocks are placed in the limiting grooves.
[0007] Preferably, the cover plate is made of plastic.
[0008] Preferably, the SIM card slot has arc-shaped clearance grooves on both sides to facilitate the placement and removal of the SIM card.
[0009] Preferably, a positioning post is provided at the lower end of the outer casing, and a positioning hole is provided on the PCB printed circuit board to cooperate with the positioning post.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] The PIN pins have been changed to spring-loaded type. The spring-loaded PIN pins and the protrusions on the bottom of the cover plate work together to effectively contact the SIM card, prevent loosening, and ensure signal stability. The outer metal shell has been changed to a sliding plastic cover plate, which is intended to fix the SIM card and make it easy to disassemble and remove the cover plate. Attached Figure Description

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0020] Please see Figures 1 to 6 The embodiments of this utility model include:
[0021] A sliding SIM card holder includes a housing 1, PIN pins 2, a cover plate 3, and a PCB printed circuit board 4.
[0022] The top surface of the outer casing 1 is provided with a SIM card placement slot 10. The SIM card placement slot 10 is provided with arc-shaped clearance slots 11 on both sides to facilitate the placement and removal of the SIM card. Each side of the outer casing 1 is provided with a row of PIN pin slots 12 for placing PIN pins 2, which communicate with the SIM card placement slot 10. The two sides of the outer casing 1 are provided with mounting parts 13 extending upward. The two mounting parts 13 are provided with sliding grooves 14 for sliding the cover plate 3. The mounting part 13 at the top of the sliding groove 14 is also provided with a limiting groove 15 for limiting the sliding trajectory of the cover plate 3. The lower end of the outer casing 1 is provided with a PCB printed circuit board 4. The lower end of the outer casing 1 is provided with a positioning post 16 extending downward. The PCB printed circuit board 4 is provided with positioning holes that cooperate with the positioning post 16.
